According to the wasm js-spec, the table index can be uint32. The
implementation in our implementation expected an int though. We did not
check for the int overflow.
I replaced the throwing of the exception in WasmTableObject::Get to use
the ErrorThrower instead of throwing the exception with Isolate::Throw
directly. The reason is that I see with other CL's that I have to throw
several errors, and I don't want to introduce a new message and
MessageId for every error. Moreover, the ErrorThrower is a standard way
in wasm to throw errors. It feels right to throw the error the same way
here.
